The Temperature Regulating Sheet Set.

Using a fabric developed for NASA to help astronauts adapt to extreme temperature fluctuations, these sheets prevent overheating or eliminate chills to create an optimal sleeping climate. Imbedded in the sheets are millions of invisible microcapsules that absorb excess heat when you are hot and release the stored heat when you are cold, ensuring a comfortable bed temperature and humidity. Unlike an electric blanket, the microcapsules adjust independently to an individual's climate, allowing two sleepers with different temperature preferences to remain comfortable throughout the night. The 300-thread count blended cotton fabric is impeccably soft and machine washable. Includes one fitted sheet and one flat sheet, and pillowcases. Green, Blue, Sand, White.

I bought these sheets because they claim to be COOL. Disappointed -- no cooling. Very nice sheets, but too expensive to not deliver what they claim to deliver.

Bottom LineNo, I would not recommend this to a friend

I bought these for my 9 year old daughter who has trouble sleeping. The sheets have been a great tool to have in the tool box and she is sleeping much better with them. I am going to buy a set for my son (7) and us as well.
